Abstract

The chain (23), accommodated in pockets (9) of the blade wheel device, pushes by means of a holder arrangement print examples (17) continuously out of the pockets to form the heaped print example flow. The holder arrangement is formed by grippers (43, 57) arranged on the chain. The grippers have jaws which come into contact with each other via the intermediary of the print examples. The first jaw is formed by a chain component and the second jaw is a part of a lever (43) pivotably located in the chain component. The lever is provided with a spring, which effects the setback of the gripper into the opening position.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Auslage von Druckexemplaren aus einer Schaufelradanordnung zur Bildung eines geschuppten Druckexemplarstroms gemäß Oberbegriff des Anspruchs 1. The present invention relates to a device for Display of printed copies from a paddle wheel arrangement to form a shingled print copy stream according to Preamble of claim 1.

Aus der EP-A-0 307 889 ist eine Vorrichtung mit einer Schaufelradanordnung bekannt, die mehrere auf einer gemeinsamen Achse sitzende axial beabstandete Schaufelräder aufweist. An jedem Schaufelrad sind in bestimmten Abständen Schaufelblätter ausgebildet, die zwischen sich Taschen zur Aufnahme von Druckexemplaren definieren. Zwischen den Schaufelrädern ist mindestens eine endlose Kette geführt, an der in gleichen Abständen zueinander Winkel- und Klemmstücke angebracht sind. Die Winkelstücke dienen einerseits als Anschlag für das in eine Tasche hineingleitende Druckexemplar und andererseits zu dessen definierten Herausschieben aus der Tasche beziehungsweise Ablegen auf ein Förderband, so daß ein geschuppter Druckexemplarstrom entsteht. Das Klemmstück wirkt zudem auf die Oberseite des Druckexemplars ein und drückt es auf das die Schaufelradtasche bildende untere Schaufelblatt. Da die Kette und das Schaufelrad bezüglich der Schaufelradachse axial versetzt sind, wird das Druckemplar scherenförmig geklemmt, wobei es ein "wellenförmiges" Profil erhält. From the EP-A-0 307 889 is a device with a paddle wheel arrangement known, the several sitting on a common axis has axially spaced paddle wheels. On everyone Paddlewheels are paddle blades at certain intervals trained to hold pockets between them Define print copies. Is between the paddle wheels run at least one endless chain, on the same in Distances to each other angle and clamping pieces are attached. The contra-angles serve on the one hand as a stop for the in a pocket of printed copy sliding in and on the other hand too its defined pushing out of the pocket or placing on a conveyor belt so that a shingled print copy stream arises. The clamp works also on the top of the printed copy and presses it on the lower airfoil forming the bucket wheel pocket. Since the chain and the paddle wheel with respect to the Paddlewheel axis are axially offset, the printed copy scissor-like clamped, with a "wavy" profile receives.

Der Nachteil dieser Vorrichtung ist darin zu sehen, daß das Druckexemplar auf das Schaufelblatt gedrückt wird, wobei die entstehende Reibungskraft dem Herausschieben aus der Tasche hinderlich ist. Im übrigen ist ein Abschmieren der Unterseite des Druckexemplars nicht auszuschließen. The disadvantage of this device is the fact that Print copy is pressed onto the airfoil, the   the resulting frictional force prevents it from being pushed out of the pocket. Furthermore Lubrication of the underside of the printed copy cannot be ruled out.

FR-A-2 387 181 bezieht sich auf eine Vorrichtung zum Bilden eines kontinuierlichen Stromes von Druckprodukten gemäß dem Oberbegriff von Anspruch 1, die ubereinanderliegend ausgelegt werden. Greifelemente, die an einer Kette um ein Kettenrad umlaufen, weisen ein stationäres sowie ein relativ zum stationär betätigbares Greifelement auf. Die Betätigung der bewegbaren Greifelemente erfolgt durch Stifte, die am Kettenrad 4 aufgenommen sind. FR-A-2 387 181 relates to an apparatus for forming a continuous stream of printed products according to the preamble of claim 1, which are laid out one above the other. Gripping elements that a chain around a sprocket, have a stationary and a relative to stationary gripping element. The actuation of the movable gripping elements is done by pins that are added to the sprocket 4.

CH-A-427625 betrifft ein Verfahren und eine Einrichtung zum verschränkten Paketieren von gefalzten Druckprodukten. Eine Kette mit hintereinander angeordneten Greifelementen läuft um ein Kettenrad um und erfährt bei der Umlenkung eine zwischen 180° und 270° liegende Umlenkung. Die Führung der Kette um das Kettenrad ist durch den Förderpfad der Kette vorgegeben, so daß sich die Kette bei der Führung um das Kettenrad fest um dessen Kontur anschmiegt. CH-A-427625 relates to a method and a device for entangled packaging of folded printed products. A chain with gripping elements arranged one behind the other runs around a sprocket and experiences a deflection between 180 ° and 270 ° lying deflection. The chain is guided around the sprocket through the conveyor path given the chain, so that the chain around the sprocket firmly around whose contour hugs.

EP-A-0 033 300 offenbart einen selbsttätigen Greifer für Kettenausleger von Druckmaschinen. Dieser für Kettenausleger von Druckmaschinen bestimmte, auf einer Gliederkette befestigter Greifer besteht aus einem starten mit Auflage- und Anschlagfläche versehenen vorlaufenden Teil und einem auf Kettenglied angebrachten Federelement, das mit seinem freien Schenkel bei gestreckter Kettenlage mit Federdruck auf die Auflagefläche einwirkt. Durch Umlenken der Gliederkette werden die Greifer automatisch geöffnet und wieder geschlossen. EP-A-0 033 300 discloses an automatic gripper for chain arms from Printing machines. This is intended for chain delivery of printing machines, on one Link chain attached gripper consists of a start with a support and stop surface provided leading part and a spring element attached to a chain link, the with his free leg in a stretched chain position with spring pressure on the Contact surface acts. By redirecting the link chain, the grippers become automatic opened and closed again.

GB-A-2 068 892 offenbart einen Förderer. Um ein Kettenrad umlaufende an verschiedenen Traktionselementen aufgenommene Greifelemente ergreifen in offenen Taschen eines Zellenrades geförderte Produkte an deren Rücken und fördern diese in vertikale Richtung. Bei der Förderung in vertikale Richtung treten die Greiferelemente in einen Kanalabschnitt 9 ein, in welchem rotierende höhenverstellbare Oberflächen vorgesehen sind, welche die Schließstellung der Greifer wieder entriegeln. GB-A-2 068 892 discloses a conveyor. Around a sprocket rotating at different Gripping elements picked up by traction elements grip one in open pockets Cellular conveyed products on their back and convey them in the vertical direction. When conveying in the vertical direction, the gripper elements step into one Channel section 9, in which rotating height-adjustable surfaces are provided which unlock the closed position of the grippers.  

Die Aufgabe der vorliegenden Erfindung besteht deshalb darin, eine materialschonende, mit präzisem Schuppenabstand erfolgende Auslage von Druckexemplaren zu erzielen. The object of the present invention is therefore to provide a material-friendly, to achieve the delivery of printed copies with precise scale spacing.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. This object is solved by the features of claim 1.

Der Vorteil des erfindungsgemäßen an der Kette ausgebildeten Greifers besteht darin, daß das in der Schaufelradtasche liegende Druckexemplar lediglich seinem Eigengewicht unterworfen ist. Eine zusätzliche Kraftbeaufschlagung, die zu einer Erhöhung der Auflagekraft auf dem Schaufelblatt führt, ist erfindungsgemäß nicht vorgesehen. Damit läßt sich einerseits die dem Herausschieben entgegenwirkende Reibungskraft vermindern und andererseits die Druckexemplarunterseite schonen. The advantage of the gripper designed according to the invention on the chain is that the printed copy in the paddlewheel pocket is only its own weight is subject. An additional application of force that leads to an increase in Contact force on the airfoil is not provided according to the invention. In order to on the one hand, the frictional force counteracting the pushing out can be reduced and on the other hand protect the underside of the printed copies.

Die an der Kette ausgebildeten Greifer werden vorzugsweise durch zwei gegeneinander tretende Backen gebildet, die das Druckexemplar zwischen sich einklemmen, wobei die beiden Backen vorzugsweise direkt gegenüber liegen, so daß ein scherenförmiges Klemmen vermieden wird. The grippers formed on the chain are preferably opposed by two kicking jaws formed, which pinch the printed copy between them, the both jaws are preferably directly opposite, so that a scissor-shaped Pinching is avoided.

In einer Weiterbildung der Erfindung wird die erste Backe von einem Kettenglied gebildet, während die zweite Backe Teil eines Hebels ist, der schwenkbar im Kettenglied gelagert ist. Damit läßt sich die Klemmfunktion sehr einfach durch Verschwenken des Hebels erzielen. In a development of the invention, the first jaw is formed by a chain link, while the second jaw is part of a lever which is pivotally mounted in the chain link is. So that the clamping function can be very easily by pivoting the lever achieve.

Um den Hebel und damit die zweite Backe in die Öffnungsstellung zurückzuführen, ist diesem Hebel eine Feder zugeordnet, wobei vorzugsweise eine Drehfeder Verwendung findet, die um die Schwenkachse gewickelt ist und deren beiden Enden im Kettenglied gehalten sind, wobei ein Ausleger der Feder am Hebel in geeigneter Weise anliegt. To return the lever and thus the second jaw to the open position a spring associated with this lever, preferably using a torsion spring finds that is wound around the pivot axis and their   both ends are held in the chain link, with a boom the spring rests on the lever in a suitable manner.

Das Schließen des Greifers wird vorzugsweise dadurch bewirkt, daß der Hebel eine Steuerfläche aufweist, die mit einer ortsfesten Steuerkurve in Kontakt kommt. Dabei drückt die Steuerkurve den Hebel, das heißt die zweite Backe, gegen die am Kettenglied ausgebildete erste Backe. The gripper is preferably closed by that the lever has a control surface which with a stationary control curve comes into contact. The presses Control curve the lever, that is, the second jaw, against the first jaw formed on the chain link.

Die Anbringung einer solchen Steuerkurve wird dadurch erleichtert, daß der Hebel als Doppelhebel ausgebildet ist, wobei der erste Hebelarm die zweite Backe aufweist, und der zweite Hebelarm, der vorzugsweise auf der gegenüberliegenden Seite des Kettenglieds herausragt, die Steuerfläche aufweist. The attachment of such a control curve is thereby relieved that the lever is designed as a double lever, wherein the first lever arm has the second jaw, and the second lever arm, which is preferably on the opposite Side of the chain link protrudes, which has control surface.

Vorzugsweise ist dieser zweite Hebelarm flexibel ausgebildet, so daß die Druckexemplare mit einer durch die Flexibilität dieses Hebelarms bestimmten Kraft geklemmt werden. Desweiteren lassen sich mit einem solchen flexiblen Hebelarm Druckexemplare unterschiedlicher Dicke greifen, ohne eine Veränderung der Steuerkurve vornehmen zu müssen. This second lever arm is preferably flexible, so that the printed copies with one through the flexibility this lever arm certain force are clamped. Furthermore, with such a flexible lever arm Printed copies of different thicknesses grip without one To have to change the control curve.

Um im Bereich der Steuerkurve die Kette daran zu hindern, der von der Steuerkurve auf die Steuerfläche aufgebrachten Kraft auszuweichen, wird eine Führung der Kette im Bereich der Steuerkurve vorgesehen. Die se Führung besteht vorzugsweise aus einem U-Profil, dessen beide Schenkel mit in Längsrichtung verlaufenden Nuten versehen sind, in die an jedem Kettenglied ausgebildete Fortsätze, vorzugsweise die beiden Enden der Schwenkachse des Hebels oder die beiden Enden eines Kettenstifts, eingreifen. Ein zusätzlicher Effekt dieser Führung ist auch darin zu sehen, daß die Kette in diesem Bereich nicht in Schwingungen geraten kann, die zu unterschiedlichen Schuppenabständen führen würden. To prevent the chain from moving in the area of the control cam force applied by the control curve to the control surface evasion will be a The chain is guided in the area of the control cam. The se leadership preferably consists of a U-profile, the both legs with longitudinal grooves are provided in the formed on each chain link Extensions, preferably the two ends of the pivot axis of the Engage the lever or the two ends of a chain pin. An additional effect of this guidance is there too see that the chain does not vibrate in this area can come to different scale distances would lead.

Die Innenkontur des Schaufelblatts 11 und die gegenüberliegende Außenkontur 15 des benachbarten Schaufelblatts bilden einen Einlauftrichter, der den Eintritt eines Druckexemplars 17 in die Tasche 9 begünstigt. Durch die bogenförmige Ausgestaltung der Schaufelblätter 11 erhalten die Taschen 9 eine Profilierung, die eine Verlangsamung des in die Tasche eingleitenden Druckexemplars 17 bewirkt, bevor dieses am Taschengrund 19 anstößt. Auf der Antriebswelle 5 sitzt zu dem Schaufelrad 3 in Längsrichtung beabstandet ein Kettenrad 21, das eine endlose Kette 23 antreibt. Auf die genaue Ausgestaltung der Kette soll später noch eingegangen werden. In Figure 1 is a paddle wheel assembly 1 in the area Print copy storage shown.

The Direction of rotation is indicated by arrow 7. in the Paddle wheel pockets 9 are formed, which in Circumferential direction are limited by blades 11. The Inner contour of the airfoil 11 and the opposite Outer contour 15 of the adjacent airfoil form one Inlet funnel, which prevents the entry of a printed copy 17 in the pocket 9 favors. Due to the arched design the blades 11 receive the pockets 9 a Profiling that slows down the pocket introductory printed copy 17 causes before this on Taschengrund 19 abuts. Sitting on the drive shaft 5 Paddle wheel 3 spaced apart in the longitudinal direction is a chain wheel 21,   that drives an endless chain 23. Exactly The design of the chain will be discussed later.

Unterhalb des Schaufelrads ist eine Ablage 25 angeordnet, auf die der geschuppte Druckexemplarstrom zumindest teilweise abgelegt wird. Jener Endabschnitt der Ablage 25, der zuerst mit den Druckexemplaren 17 in Kontakt kommt, ist dabei bogenförmig ausgebildet, um so den Abstand zum benachbarten Schaufelblatt möglichst gering zu halten. Dieser bogenförmige Abschnitt geht jedoch in einen horizontal verlaufenden Abschnitt über, an dessen Ende sich ein Förderband 27 anschließt. Auf dieses Förderband werden die Druckexemplare 17 in definierten Abständen zueinander nun vollständig abgelegt und als geschuppter Druckexemplarstrom beispielsweise zu einer nachfolgenden Bearbeitungsstation in Pfeilrichtung transportiert. A shelf 25 is arranged below the paddle wheel that the shingled print copy stream at least partially is filed. That end portion of the tray 25 that is first comes into contact with the printed copies 17 arcuate, so the distance to the neighboring To keep the airfoil as low as possible. This arcuate However, section goes into a horizontal one Section about, at the end of which a conveyor belt 27th connects. The printed copies are on this conveyor belt 17 at defined intervals to each other now completely filed and as a scaled print copy stream for example to a subsequent processing station in Arrow direction transported.

Die Kette 23 wird zum Rand des Schaufelrads 3 in Richtung des Förderbands 27 schräg nach unten geführt und im Bereich des ebenen Abschnitts der Ablage 25 von einer Umlenkrolle 29 in die Horizontale umgelenkt und parallel zum Förderband 27 weitergeführt. Im weiteren Verlauf wird dann die Kette 23 durch eine weitere Umlenkrolle 31 vom Förderband 27 weg- und zum Kettenrad 21 zurückgeführt. The chain 23 is to the edge of the paddle wheel 3 in the direction of Conveyor belt 27 guided obliquely downwards and in the area of flat portion of the tray 25 from a pulley 29 in the horizontal deflected and parallel to the conveyor belt 27 continued. In the further course, the chain 23 by a further deflection roller 31 away from the conveyor belt 27 and returned to the sprocket 21.

Die Kette 23 setzt sich aus einzelnen Kettengliedern 33 zusammen, die über Kettenstifte 35 miteinander schwenkbar verbunden sind. Eine genauere Darstellung eines Kettenglieds 33 ist in der Figur 2 gezeigt. The chain 23 is composed of individual chain links 33 together, pivoted together via chain pins 35 are connected. A more accurate representation of a Chain link 33 is shown in FIG. 2.

Jedes Kettenglied 33 besteht aus einem Grundkörper 36, in den ein Durchbruch 42 eingebracht ist, wobei den Laschen eines üblichen Kettenglieds vergleichbare seitenwände 37 entstehen. An einem Längsende des Grundkörpers 36 ist ein Fortsatz 39 ausgebildet, der den Kettenstift 35 aufnimmt. Die Kettenstiftlänge ist dabei etwas größer als die Breite des Grundkörpers 36 gewählt, so daß der Kettenstift mit einer später noch beschriebenen Führung zusammenwirken kann. Ansonsten entspricht die Kettenstiftlänge der Breite des Grundkörpers. Each chain link 33 consists of a base body 36, in the an opening 42 is introduced, the tabs one usual chain link comparable side walls 37 arise. At one longitudinal end of the base body 36 there is an extension 39 formed, which receives the chain pin 35. The Chain pin length is slightly larger than the width of the   Base body 36 selected so that the chain pin with a Leadership described later can cooperate. Otherwise the chain pin length corresponds to the width of the Basic body.

Am anderen Längsende des Grundkörpers ist eine nach unten offene Ausnehmung 41 vorgesehen, in die der Fortsatz 39 und der Kettenstift 35 des nächsten Kettenglieds einsteckbar ist. Die Abmessungen der Ausnehmung 41 sind dabei so gewählt, daß eine Schnappverbindung ermöglicht wird. At the other longitudinal end of the body is one down open recess 41 is provided, in which the extension 39 and the chain pin 35 of the next chain link can be inserted. The dimensions of the recess 41 are chosen so that a snap connection is made possible.

Diese vorzugsweise aus Kunststoff bestehenden Kettenglieder 33 können sehr einfach zusammengefügt werden, so daß die in der Schaufelradanordnung benutzte Kette leicht verlängert oder verkürzt werden kann. These are preferably made of plastic Chain links 33 can be assembled very easily, so that the chain used in the paddle wheel assembly is light can be extended or shortened.

In dem zwischen Kettenstift 35, den beiden Seitenwänden 37 und dem Fortsatz 39 gebildeten Freiraum 42 ist ein Hebel 43 eingebracht, der über eine Schwenkachse 45 mit den Seitenwänden 37 schwenkbar verbunden ist. Der Übersichtlichkeit wegen ist dieser Hebel in Figur 2b nicht gezeigt. In between chain pin 35, the two side walls 37 and the extension 42 formed by the free space 42 is a lever 43 introduced that with a pivot axis 45 with the Side walls 37 is pivotally connected. Of the For reasons of clarity, this lever is not shown in FIG. 2b shown.

Der Hebel 43 durchgreift den Freiraum 42 vollständig und ragt auf beiden Seiten des Kettenglieds 33 hervor. Dieser Hebel 43 wird über eine Feder, vorzugsweise eine Drehfeder, mit einer Rückstellkraft beaufschlagt, die den Hebel in eine Grundstellung zwingt, die in Figur 2a gestrichelt dargestellt ist. The lever 43 extends completely through the free space 42 and protrudes on both sides of the chain link 33. This lever 43 is with a spring, preferably a torsion spring Restoring force applied to the lever in one Basic position forces that shown in dashed lines in Figure 2a is.

In Figur 3 ist diese Feder 47 in der Draufsicht gezeigt. Dabei ist erkennbar, daß es sich um eine Drehfeder handelt, die zu beiden Seiten des Hebels 43 um die Schwenkachse 45 gewickelt ist, wobei die beiden Enden 49 jeweils eine Seitenwand 37 untergreifen, so daß diese Enden beim Spannen der Feder ein Widerlager finden und nicht ausweichen können. In Figure 3, this spring 47 is shown in plan view. It can be seen that it is a torsion spring, on both sides of the lever 43 about the pivot axis 45 is wound, the two ends 49 each one Reach under side wall 37 so that these ends when tightening find an abutment of the spring and cannot avoid it.  

Selbstverständlich können sich die beiden Enden auch an anderen geeigneten Stellen, beziehungsweise einer Seitenwand 40 des Durchbruchs 42, abstützen, wie in Figur 4 gezeigt. Of course, the two ends can also other suitable places, or one Support side wall 40 of opening 42, as in FIG. 4 shown.

Auf den Hebel wirkt ein die beiden Wicklungen verbindender Ausleger 51 ein, der den Hebel 43 mit einer die Rückstellung bewirkenden Kraft beaufschlagt. Andererseits ist diese Ausgangsstellung beziehungsweise Grundstellung durch einen Anschlag 53 begrenzt, der wie in Figur 2a sichtbar durch das Ende des Fortsatzes 39 des nachfolgenden Kettenglieds gebildet ist. Gegen diesen Anschlag 53 wird eine dafür ausgebildete Anschlagfläche 55 des Hebels 43 durch die Feder 47 gedrückt. A lever connecting the two windings acts on the lever Boom 51, the lever 43 with a the provision acting force. On the other hand, this is Starting position or basic position by one Stop 53 limited, as shown in Figure 2a by the End of the extension 39 of the subsequent chain link is formed. Against this stop 53 is one for it trained stop surface 55 of the lever 43 by the Spring 47 pressed.

Das Kettenglied 33 weist an seinem die Ausnehmung 41 tragenden Ende eine nach oben hervorspringende Nase 57 auf, deren zur Kettengliedmitte gerichtete Seitenfläche 59 als Anschlag für den Hebel 43 bei einer Hebelbewegung gegen die Federkraft dient. Somit wird durch das Zusammenwirken des Hebels 53 mit der Seitenfläche 59 ein Greifer ausgebildet. wobei die Seitenfläche 59 als eine erste Backe und der dieser Fläche zugewandte Abschnitt des Hebels 43 als eine zweite Backe dient. Zwischen den Backen kann dann beispielsweise ein Druckexemplar eingeklemmt werden. The chain link 33 has the recess 41 on it carrying end has an upwardly projecting nose 57, whose side surface 59 facing the chain link center as Stop for the lever 43 during a lever movement against the Spring force serves. Thus, through the interaction of the Lever 53 formed with the side surface 59 a gripper. the side surface 59 as and a first jaw Area facing portion of lever 43 as a second Cheek serves. Then, for example, between the jaws Print copy can be pinched.

Die Klemmbewegung des Hebels 43, also eine Drehung um die Schwenkachse im Uhrzeigersinn, wird in dem in Figur 2a gezeigten Beispiel dadurch bewirkt, daß das der zweiten Backe 61 gegenüberliegende Ende 63 des Hebels 43 auf eine ortsfeste Steuerkurve 65 aufläuft. The clamping movement of the lever 43, that is, a rotation about the Swivel axis clockwise, is in the in Figure 2a shown example causes that the second Cheek 61 opposite end 63 of the lever 43 on one stationary control curve 65 runs up.

Das Schließen der aus den beiden Backen 59 und 61 bestehenden Klemmeinrichtung läuft dabei so ab, daß das als Steuerfläche dienende Hebelende 63 während der Bewegung des Kettenglieds in Pfeilrichtung auf die zunächst geneigte Steuerkurve 65 aufläuft, wie dies in Figur 2a gestrichelt dargestellt ist. Durch die kontinuierliche Verringerung des Abstands zwischen der Schwenkachse 45 und der Steuerkurve 65 wird der untere Hebelarm mit der Steuerfläche 63 nach hinten gegen die Transportrichtung der Ketten gedrückt und folglich im Uhrzeigersinn gedreht. Dadurch nähert sich die am anderen Hebelarm ausgebildete Backe 61 der ersten Backe, das heißt der Seitenfläche 59 der Nase 57. Ist die gewünschte Endposition erreicht, wird die Steuerkurve 65 parallel zur Transportrichtung des Kettenglieds 33 weitergeführt, wobei eine gleichbleibende Klemmkraft aufrechterhalten wird. The closing of the two jaws 59 and 61 Clamping device runs so that that as a control surface serving lever end 63 during movement of the chain link in the direction of the arrow onto the initially inclined cam 65   accumulates, as shown in dashed lines in Figure 2a. By continuously reducing the distance between the pivot axis 45 and the cam 65 becomes the lower one Lever arm with the control surface 63 back against the Direction of transport of the chains pressed and consequently in Turned clockwise. This brings the other closer Lever arm designed jaw 61 of the first jaw, that is the side surface 59 of the nose 57. Is the desired Reached end position, the control cam 65 is parallel to Direction of transport of the chain link 33 continued, wherein a constant clamping force is maintained.

Sobald die Steuerfläche 63 am Ende der Klemmung den Kontakt mit der Steuerkurve 65 verliert, wird der Hebel in die Grundposition, bedingt durch die Rückstellkraft der Feder 47, zurückgestellt. Once the control surface 63 contacts the end of the clamping loses with the cam 65, the lever is in the Basic position, due to the restoring force of spring 47, deferred.

In Figur 4 ist eine weitere Ausgestaltung des Hebels 43 gezeigt, wobei das Kettenglied als solches mit dem eben beschriebenen übereinstimmt. Auf eine nochmalige Beschreibung der mit gleichen Bezugszeichen bezeichneten Teile wird deshalb verzichtet. FIG. 4 shows a further embodiment of the lever 43 shown, the chain link as such with the plane described. On another description the parts designated by the same reference numerals therefore waived.

Im Unterschied zu dem zuvor genannten Hebel 43 weist der in Figur 4 gezeigte Hebel einen flexiblen die Steuerfläche tragenden Hebelarm 67 auf. Dieser bogenförmig ausgebildete flexible Hebelarm 67 ermöglicht es, die Anpreßkraft der Backe 61 an die gegenüberliegende Backe 59 durch geeignete Materialwahl beziehungsweise Formgebung einzustellen beziehungsweise vorzugeben. In contrast to the lever 43 mentioned above, the in Figure 4 lever shown a flexible control surface bearing lever arm 67. This arched flexible lever arm 67 allows the pressure of the jaw 61 to the opposite jaw 59 by suitable Material choice or shape to adjust or to specify.

Damit ist die Einhaltung eines genau definierten Abstands zwischen Steuerkurve 65 und Schwenkachse 45 zur Erzielung einer gleichbleibenden Klemmung, wie dies nach dem Ausführungsbeispiel gemäß Figur 2a erforderlich ist, nicht mehr notwendig. Der für eine Klemmung erforderliche Mindestabstand zwischen Steuerkurve 65 und Schwenkachse 45 kann somit unterhalb eines gewissen Toleranzbereich gewählt werden. Auch Druckexemplare unterschiedlicher Dicke können ohne Veränderung der Steuerfläche geklemmt werden. This means maintaining a precisely defined distance between cam 65 and pivot axis 45 to achieve a constant clamping, like this after the Embodiment according to Figure 2a is not required more necessary. The one required for clamping   Minimum distance between cam 65 and swivel axis 45 can therefore be selected below a certain tolerance range become. Printed copies of different thicknesses can also be printed can be clamped without changing the control surface.

Im folgenden soll nun mit Bezug auf die Figur 1 das Zusammenwirken von Kette 23 und Schaufelrad 3 erläutert werden. In the following, the Interaction of chain 23 and paddle wheel 3 explained become.

Zunächst gelangt ein beispielsweise zuvor gefalztes Druckexemplar 17 in eine Tasche 9 des Schaufelrads 3, wobei das Druckexemplar 17 bis zum Taschengrund 19 gleitet. Anschließend stößt die am Taschengrund 19 anliegende Kante des Druckexemplars 17 an die die Nase 57 aufweisende Seite des Kettenglieds an. Dies wird durch das sich drehende Schaufelrad 3 und die schräg zum Schaufelradrand laufende Kette 23 bewerkstelligt. First, for example, a previously folded one arrives Printed copy 17 in a pocket 9 of the paddle wheel 3, wherein the printed copy 17 slides to the bottom of the pocket 19. Then the edge abutting the pocket base 19 of the printed copy 17 to the side having the nose 57 of the chain link. This is due to the spinning Paddle wheel 3 and the one running diagonally to the edge of the paddle wheel Chain 23 accomplished.

Durch eine vom Abstand der einzelnen Taschen 9 abhängigen Längenausdehnung der einzelnen Kettenglieder wird erreicht, daß das Druckexemplar 17 zwischen dem die Backe 61 aufweisenden in der Grundstellung befindlichen Hebelarm 43 und der Nase 57 zu liegen kommt. Durch die abwärts gerichtete Bewegung der Kette 23 und die Drehbewegung des Schaufelrads 3 wird das Druckexemplar 17 langsam aus der Tasche 9 des Schaufelrads 3 geschoben und zunächst auf der Ablage 25 teilweise abgelegt. Gleichzeitig wird die bereits mit Figur 2a beschriebene Klemmfunktion ausgeführt, indem die Steuerfläche des Hebels 43 auf die Steuerkurve 65 aufläuft und die vordere Kante des Druckexemplars zwischen den beiden Backen festklemmt. By a depending on the distance of the individual pockets 9 Linear expansion of the individual chain links is achieved, that the printed copy 17 between which the jaw 61st having lever arm 43 in the basic position and the nose 57 comes to rest. By looking down Movement of the chain 23 and the rotary movement of the paddle wheel 3 the printed copy 17 is slowly out of the pocket 9 of the Paddle wheel 3 pushed and first on the tray 25 partially filed. At the same time, the figure is already 2a described clamping function performed by the Control surface of the lever 43 runs onto the cam 65 and the leading edge of the printed copy between the two Jaws jammed.

Mit Hilfe dieser Klemmfunktion wird erreicht, daß das Druckexemplar 17 nicht zu schnell aus der Tasche 9 gleitet, was zu einer Unregelmäßigkeit des geschuppten Druckexemplarstroms führen würde. With the help of this clamping function it is achieved that Print copy 17 does not slide out of pocket 9 too quickly, resulting in an irregularity of the scaly Print copy stream would lead.  

In dem in Figur 1 gezeigten Ausführungsbeispiel bleibt das Druckexemplar 17 auch nach Verlassen der Tasche 9 zwischen den Backen 59, 61 festgeklemmt. So wird das zunächst von der Ablage 25 teilweise gestützte Druckexemplar 17 durch die Kette in Richtung des Förderbands 27 gezogen, wobei der Transport des Druckexemplars später durch das Förderband unterstützt wird. Erst wenn sich das Druckexemplar 17 vollständig auf dem Förderband 27 befindet, wird die Klemmung gelöst und das Druckexemplar entsprechend freigegeben. Ist die Geschwindigkeit des Förderbandes 27 an die Geschwindigkeit der Kette 23 angepaßt, so ergibt sich ein geschuppter Druckexemplarstrom, bei dem die einzelnen Abstände der Druckexemplare sehr genau eingehalten werden können. This remains in the embodiment shown in FIG Print copy 17 even after leaving the pocket 9 between the jaws 59, 61 clamped. So it is initially from the Tray 25 partially supported copy 17 by the Chain pulled in the direction of the conveyor belt 27, the Transport of the printed copy later through the conveyor belt is supported. Only when the printed copy 17 is located completely on the conveyor belt 27, the clamping solved and the print copy released accordingly. Is the speed of the conveyor belt 27 to the Adjusted the speed of the chain 23, this results in a scaled print copy stream, in which the individual Distances of the printed copies are observed very precisely can.

Figur 5 zeigt ein Ausführungsbeispiel einer Führung der Kette, die insbesondere in jenem Abschnitt des Kettenumlaufs vorgesehen ist, bei dem die Klemmung des Druckexemplars durchgeführt wird; mithin also im Bereich der Steuerkurve 65. Figure 5 shows an embodiment of a guide of the Chain, particularly in that section of chain circulation is provided in which the clamping of the printed copy is carried out; therefore in the area of the control cam 65.

Die Führung 69 besteht aus einem U-Profil, mit zwei Schenkeln 71 und einem Steg 73. An der Innenseite eines jeden Schenkels 71 ist eine Nut 75 eingebracht, die sich in Transportrichtung der Kette erstreckt. In diese Nuten 75 greifen entsprechende Fortsätze des Kettenglieds 33, vorzugsweise die beiden seitlich überstehenden Enden der Schwenkachse 45 beziehungsweise des Kettenstifts 35, ein. The guide 69 consists of a U-profile, with two Legs 71 and a web 73. On the inside of each Leg 71 is a groove 75 which is located in Direction of transport of the chain extends. In these grooves 75 engage corresponding extensions of the chain link 33, preferably the two laterally projecting ends of the Swivel axis 45 or the chain pin 35, a.

Die Innenfläche des Stegs 73 dient als Steuerkurve 65, die mit der Steuerfläche 63 am Hebelarm 43 zusammenwirkt, wie dies bereits in Zusammenhang mit den zuvor beschriebenen Figuren erläutert wurde. The inner surface of the web 73 serves as a cam 65, the cooperates with the control surface 63 on the lever arm 43, such as this already in connection with the previously described Figures was explained.

Die Führung des Kettenglieds 33 in der Nut 75 bewirkt, daß das Kettenglied nicht der durch die Steuerkurve 65 auf die Steuerfläche 63 des Hebels aufgebrachten Kraft nach unten ausweichen kann. Im übrigen wird ein Durchhängen beziehungsweise ein Schwingen der Kette wirkungsvoll verhindert. The leadership of the chain link 33 in the groove 75 causes the chain link is not that of the cam 65 on the   Control surface 63 of the lever applied force down can dodge. Otherwise there will be sagging or swinging the chain effectively prevented.

Am Beginn der Steuerkurve 65 können die Nuten 75 - in Umlaufrichtung der Kette gesehen - trichterförmig geöffnet sein, um ein Einlaufen der beiden Schwenkachsenenden in die Nuten 75 zu erleichtern. At the beginning of the cam 65, the grooves 75 - in Direction of rotation of the chain seen - opened like a funnel to ensure that the two swivel axis ends enter the To facilitate grooves 75.

In Figur 6 ist in schematischer Darstellung eine Schaufelradanordnung 1 gezeigt, die aus mehreren auf einer Antriebswelle 5 sitzenden Schaufelrädern 3 und dazwischenliegenden Kettenrädern 21 besteht, wobei die Antriebswelle 5 und damit die Kettenräder 21 und die Schaufelräder 3 beispielsweise über einen Riemenantrieb 77 angetrieben werden. In Figure 6 is a schematic representation Paddle wheel assembly 1 shown, which consists of several on one Drive shaft 5 seated paddle wheels 3 and there are intermediate sprockets 21, the Drive shaft 5 and thus the sprockets 21 and Bucket wheels 3, for example via a belt drive 77 are driven.

Selbstverständlich ist die vorliegende Erfindung auch auf andere Schaufelradanordnungen anwendbar, die beispielsweise nur zwei oder drei beziehungsweise mehr als die gezeigten vier Schaufelräder aufweisen, wobei es genügt, lediglich eine Kette mit den Greifern zu versehen. Of course, the present invention is also based on other paddle wheel arrangements applicable, for example only two or three or more than those shown have four paddle wheels, it being sufficient to have only one To provide the chain with the grippers.
